Learn how to determine the nth term of a geometric sequence

The video tutorial explains how to find the n-th rule for a geometric sequence. It begins by introducing the concept and the need for a rule to determine any term in the sequence. The instructor then labels the terms and identifies the first term. The process of calculating the ratio by dividing a term by its previous term is explained. Finally, the general rule for the sequence is derived, showing how to express any term using the first term and the ratio.
